Answer:
12
Step-by-step explanation: If you made x, 4 and y, 5 then all equations would make sense if you change the letters to numbers.
IF
(3*4)+(4*10)=52
and
(5*4)+10=30
then
<h2>
(8*4)-2*10=<u><em>
12</em></u></h2><h2 />
Answer:
6600
Step-by-step explanation:
y = 15000( 1.2) ^ (x/3)
Let x = 6 years
y = 15000( 1.2) ^ (6/3)
y = 15000( 1.2) ^ (2)
y = 15000( 1.44)
y =21600
This is the total amount in the account
We want the profit
Subtract the original amount in the account
21600-15000
6600
Answer:
2.20752 x 
Step-by-step explanation:
The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.
- 365 days refer to the total number of days per year
- 86,400 seconds refer to the number of seconds per day
Let's solve.
- 365 x 86,400 = 31,536,000 or 3.1536 x

<em>Therefore, one year has 3.1536 x </em>
<em> seconds.</em>
Next, you have to know the number of seconds in 10 billion years.
- (3.1536 x
) x (1.0 x
) = 3.1536 x 
The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.
- (3.1536 x
) x 7,000,000 = 2.20752 x 
<u>Answer:</u>
○ 
<u>Step-by-step explanation:</u>
To find the equation of the line, let's first consider the points whose coordinates we have been given:
• (6, 1)
• (2, 0).
The point (2, 0) is what is called the x-intercept, which is the point where the line crosses the x-axis. This means that at this point, the y-coordinate of the line is 0.
Next, let's calculate the slope (gradient) of the line using the formula:

where:
m = gradient,
and
= points on the line.
Using the formula:

⇒ 
Finally, now that we have two points on the line as well as the line's slope, we can use the following formula to find the equation of the line:

You can use any of the points on the line as
and
.
Using (2, 0):

⇒ 
Therefore the equation of the line is
.
